Intuit owns the financial software that runs much of American small business and household tax life. QuickBooks anchors the company as the default accounting system for small firms, TurboTax dominates self-filed taxes, and Credit Karma and Mailchimp extend the reach into consumer finance and marketing. The strategy layers AI assistance and live human experts on top of software subscriptions, raising revenue per customer. Founded in 1983, Intuit has survived repeated platform shifts by repurchasing its own disruption early.
